I know the answer but I won't spoil the fun yet.
Incoming solar radiation warms the earth, but it takes the earth approx 2 months to radiate the heat it captured from the sun.
In NY for example, Dec 21st shortest amount of light, so 2 months later should be cold, Feb21st. During Summer solstice 2 months later also, so approx Aug is highest temps.
Also we are closer to the sun now I think, but the angle of incoming solar radiation is more important.

Actually, the coldest days, statistically, are during the 3rd & 4th week of January. Then it slowly begins to rise. conversely, it will be the 3rd & 4th week of July when it is statistically the warmest.
